Using the SPA heater control relay

The SPA heater driver system consists of a power relay (230V50Hz / 30A) which plugs into
the heater phase wire (between the SPA heater controller output and the heater itself).
This relay is controlled by the heat pump control box either automatically or manually (boost).
As such, for the system to work properly, it is imperative to set the desired temperature of
the SPA water to the maximum on the SPA control screen and to programme the filtration
time. In this way, the actual temperature setting will now be done on the heat pump or via the
smartphone application.
- In automatic spa heater mode: When weather conditions become difficult for the heat pump
(C5 setting: outside temperature below a specified temperature, adjustable from -25 to 20°C)
and the desired bathing temperature is higher than the measured water temperature (C6 setting,
adjustable from 1 to 5°C), the heater control relay is triggered. Thus the heating uses the electric
heater of the SPA in addition to the heat pump in order to reach the desired temperature.
- In manual spa heater mode: Regardless of the weather conditions, as soon as the deviation
between setpoint and measured temperature exceeds the set deviation (C7 setting, adjustable
from 1 to 5°C), the relay is triggered. Thus the heating uses the electric heater of the SPA in
addition to the heat pump in order to reach the desired temperature.
To use this relay:
Setting the C4 setting = 1 to activate control in automatic mode or C4 = 2 to activate control in manual
mode (see "4.9 Setting", page 63 or "User parameters", page 25).
